Unlike other ACASs (ACAS II, ACAS X), ACAS Xu can provide both vertical and horizontal resolutions. The challenge is: how to choose between vertical and horizontal maneuvers? The choice is done by a module called Nucleus. However, little information on what Nucleus might be was publicly available until last September.
Drones regulation is quickly evolving with a notable increase in complexity as more mission types appear, technology advances and public acceptability evolves. Complying with the regulation is complexe enough in a single country, and it gets even more complex for cross-border missions.
The EASA recently released some results from the « Drone Collision » task force. The goal of this study was to assess the potential risk to aircraft posed by drones of different sizes flying at different levels.
After the « Introduction of a regulatory framework for the operation of drones », the EASA is now proposing a complete prototype regulation for unmanned aircraft operation (all categories, all altitudes).
